VN7004CH

VN7004CH Description

The VN7004CH from STMicroelectronics is a high-side N-channel power switch designed for automotive-grade applications, part of the VIPOWER™ series. This obsolete device integrates a single output with a 1:1 input-to-output ratio, capable of handling up to 38A continuous current. It operates within a 4V to 28V load voltage range and features an exceptionally low Rds(on) of 4mΩ (typical), minimizing power dissipation. The OctaPAK 7+1 package ensures efficient thermal management and compact surface-mount integration.

VN7004CH Features

• High-Side Switch: Ideal for direct battery-connected loads.
• Robust Protection: Includes fixed current limiting, open-load detection, over-temperature, over-voltage, and UVLO (Undervoltage Lockout).
• Low Power Loss: 4mΩ Rds(on) enhances efficiency in high-current applications.
• Automotive Compliance: Meets stringent ROHS3 and REACH standards, suitable for harsh environments.
• Simplified Control: On/Off interface eliminates need for external voltage supply (Vcc/Vdd not required).
• Compact Packaging: OctaPAK (7 Leads + Tab) optimizes PCB space and heat dissipation.

VN7004CH Applications

• Automotive Systems: ECU power distribution, LED lighting drivers, and solenoid control.
• Industrial Load Switching: Motor drives, actuator control, and high-current relay replacements.
• Power Management: Battery protection circuits and hot-swap applications.
• Fault-Sensitive Designs: Systems requiring open-load detection or thermal shutdown for reliability.

Conclusion of VN7004CH

The VN7004CH excels in high-current switching with its low Rds(on) and integrated protections, making it a robust choice for automotive and industrial applications. While obsolete, its OctaPAK packaging and VIPOWER™ technology offer superior thermal performance and reliability compared to standard MOSFET-based switches. Engineers seeking compact, high-efficiency solutions for 28V systems will find this device particularly advantageous, despite its discontinued status.
